Do you understand now, why Win32 programs have such a size? :-)

(This is quick fix. As we actually need just four functions in addition to
mod_export'ed, it is better to define additional token that is defined on
Cygwin to __attr...)

That is really bad. Alternatives are

- compile such module into main DLL. We may somehow automate it by putting
hint into .mdd file
- pretend itself run-time linker and resolve address itself.
- rewrite zsh in C++ ...


Now I *really* have working Zsh will dynamic loading. Unfortunately,
completion is not really useable without parameters module ... just tried

zmodload zsh/mapfile
vared 'mapfile[init.syms]'

it works!
